The past month I have been gathering gathering and researching the 4/3 system. Looking at both Panasonic & Olympus. Choosing a camera system has been challenging. The bargain price of the G5 is is making it easier. At the price I've seen I could add another lens. What telephoto lens would be recommended? For those that are using the G-5 do you shot in jpeg or raw? Do you find. there is enough creativity to grow into?
